摘　　要：【目的】确定五指毛桃不同采收部位的质量。【方法】应用气相色谱 质谱联用 (GC MS)法分别对五指毛桃不同采收部位中挥发油的含量和成分以及醇提物的成分进行分析。【结果】五指毛桃根皮中挥发油的含量高于根木质部 ;五指毛桃根皮与根木质部所含的化学成分相似 ,挥发油成分以十六酸、油酸 +亚油酸、亚油酸酰胺、软脂酸酰胺、硬脂酸酰胺、邻苯二甲酸二丁酯为主 ;其乙醇提取物中以补骨脂素、十六酸、十六酸乙酯、佛手内酯、油酸、亚油酸为主。根皮中补骨脂素的含量高于木质部。【结论】五指毛桃不同采收部位所含化学成分相似 ,其中根皮部的挥发油成分和补骨脂素含量均高于木质部。To investigate the quality of different parts of Radix Fici Hirtae. The content and components of volatile oils and ethanol-extracts from different parts of Radix Fici Hirtae were analyzed by the combination of gas chromatography and mass spectrometry (GC-MS). The content of volatile oils in the cortex was higher than that in the xylem and the chemical components either in the cortex or in the xylem are similar. The main components in volatile oils are hexadecanoic acid, oleic acid+linoleic acid, linoleic acid amide, palmitic acid amide,stearic acid amide and dibutyl phthalate. The main components in ethanol-extracts are psoralen, hexadecanoic acid, hexadecanoic acid ethyl ester, bergapten, oleic acid and linoleic acid. The content of psoralen in the cortex was higher than that in the xylem.[Conclusion]The chemical components in different parts of Radix Fici Hirtae are similar but the contents of volatile components and psoralen are higher in the cortex than those in the xylem.
